| 摘 要： | 针对酒后驾车问题,根据微分方程理论以及合理的假设,建立了体液中酒精含量随时间变化的数学模型,并求得其特解.再根据给定的数据,运用MATLAB软件确定回归方程的系数.由此,对于不同的喝酒方式以及喝下的不同数量的酒,进行血液中酒精浓度的分析,可以预测喝酒后任意时刻血液中的酒精浓度,并能预测不同喝酒方式以及喝下的不同数量的酒后能否驾车的时间分界点.从而对问题作出科学的解释和证明.

| Abstract: | In this paper,we establish the differential equation concerning situation,in which a certain amount of alcohol drinks is given in a short time vs.in a long time. Each coefficient is solved,based on given data by nonlinear regression.As a result,we can forecast the of alcohol in the body fluid in the arbitrary time after drinking,and can forecast the time threshold with different drinking modes or drinking wine of different quantity.Thus we make the science explanation and the proof for the questions. |
